流体殺菌装置
Document Type and Number:
Japanese Patent JP6885279
Kind Code:
B2
Abstract:
The utility model provides a fluid sterilization device. A fluid sterilization device according to an embodiment comprises: a flow path member having a first flow path through which a fluid flows; a first light source disposed facing a flow path cross-section of the first flow path intersecting the flow direction of the fluid, the first light source having a plurality of first light-emitting elements that irradiate ultraviolet light into the first flow path; and a second light source which is disposed so as to face the flow path cross-section of the first flow path and so as to face the firstlight source, and which has a plurality of second light-emitting elements that irradiate ultraviolet light into the first flow path. When the plurality of first light-emitting elements and the plurality of second light-emitting elements are projected onto the same plane where the first light source and the second light source face each other, the first light-emitting elements and the second light-emitting elements are disposed at the apexes of the virtual regular polygons. According to the utility model, the ultraviolet irradiation efficiency of fluid in a flow path is improved.
